The invention relates to a high-efficiency
impact sand making
machine, comprising a box body, a rotor part, an
impact rack, a maintenance hanging bracket and a vibratory feeding hopper, wherein the rotor part is mounted on a lower base of the box body, the
impact rack is hung on the top of two inner sides of the box body, the maintenance hanging bracket and the vibratory feeding hopper are mounted on the top of the box body respectively, and a crushing cavity is formed between the impact rack and the rotor. Materials can be subjected to multiple-likelihood continuous impact and crushing in the crushing cavity more than twice, and multiple impact and crushing can be realized between the materials; impact lining board and flat hammer are made of
alloy material, thereby prolonging the
service time of the high-efficiency impact sand making
machine; the high-efficiency impact sand making
machine has wide feeding scope, the feeding grain size can reach 80mm; the high-efficiency impact sand making machine has high rotating speed and the linear speed of the rotor can be as high as 80m / s, thus one-step
formation rate of the materials is up to more than 60%, and the product can obtain excellent grade; the high-efficiency impact sand making machine has the advantages of being low in weight, large in feeding grain size, strong in
processing capability, high in yield, low in
energy consumption, simple in operation and convenient in maintenance.
